New Delhi:Google is in talks with the Indian government to address any concerns ​that the latter may have about the search giant’s balloon-based internet for everyone project – Loon – and has ​a solution based on spectrum sharing​​, a top executive said Wednesday.

“One of the biggest concerns has to do with impedance, whether or not we will interfere with spectrum. That's a discussion we've had with telcos around the world and we believe we have an answer to that around spectrum sharing and that we've solved that issue, in terms of sharing spectrum so that it doesn't create impedance,” Marian Croak, Vice-President of Access Strategy & Emerging Markets, told reporters.

Project Loon proposes to provide internet connectivity from balloons floating at a height of 20 km above the earth's surface on a pilot basis. The idea is to connect remote areas of the country using LTE or 4G technology through the balloons, which can transmit as far as 40 km from their diameter.

​The ​project ​however ​has run into some rough weather in the country, with at least three central ministries — defence, home and civil aviation — and the Department of Telecommunications (DoT) having raised technical and security concerns over the project, sources had told ET recently.

Union communications and IT minister Ravi Shankar Prasad recently confirmed that there are technical glitches in Project Loon. "The proposed frequency band to be used in the Loon Project of Google is being used for cellular operations in India and it will lead to interference with cellular transmissions," he said in a written reply to the Rajya Sabha.

The other concerns are related to security. While the civil aviation ministry fears that the balloons may interfere with flight paths should thus be monitored by Air Traffic Control (ATC), the home ministry has expressed fears of external surveillance through them. The defence ministry is concerned about the balloons floating over military establishments and coming in the way of military aircraft.

“We've run into this in other countries and we've been able to solve it. It's up to Google to convince the government,” Croak said.

A government official has previously said there have been several meetings between the nodal officers of these ministries and the Google team, including the ones from their headquarters in Mountain View, California. "Google has been notified in written about the concerns and now they have to get back to us with possible solutions," added the official, who spoke on condition of anonymity.

"The most important concern is that of spectrum, rest of the issues can be take care of," said another government official, who is directly involved with the discussions.

After PSU banks, the government is likely to infuse capital in two chronically ill telecom PSUs BSNL and MTNL, and the Union Cabinet is likely to take a decision on 4G spectrum allocation to them by the third week of the current month after DoT places the note before it for consideration.

At a high-level meeting at the PMO late Tuesday, it was also decided that the two telcos will frame a Voluntary Retirement Scheme (VRS) to reduce their employee strength, which will be followed by a reduction in the retirement age to 58.
